First Record of Aulacorthum solani (Hemiptera: Aphididae) Occurring on Boenninghausenia albiflora var. Japonica (Rutaceae)

Aulacorthum solani was recorded on Boenninghausenia albiflora var. japonica in Japan in 2019, where symptoms such as deformation and/or yellowing, were observed on infested leaves. Rearing experiments revealed that A. solani is able to reproduce on the same plant species. Boenninghausenia albiflora var. japonica has not been recorded as a host plant for any aphid species, including A. solani. Therefore, the present study is the first record of aphids and A. solani occurring on B. albiflora var. japonica.
